The AccuFiz laser interferometer offers an unmatched combination of performance, quality and value, for accurate, repeatable measurement of surface shape and transmitted wavefront quality. The AccuFiz is extremely easy to use in confined lab spaces. Its compact, lightweight design is extremely rigid for maximum stability in any orientation or environment.
In production environments as well as in the lab the AccuFiz provides industry leading repeatability. Only AccuFiz includes Smart Zoom™ to ensure accurate lateral resolution over the entire 1X–10X zoom range. Diffraction-limited imaging provides unparalleled resolution, particularly at mid-spatial frequencies, to measure polishing artifacts that other interferometers miss.
The AccuFiz is designed to excel in challenging conditions. With the industry’s only continuously adjustable extended source you can optimize for test conditions and reduce coherent artifacts from dust, defects and stray reflections, resulting in extremely low measurement noise. On the shop floor or in a clean room, optional Dynamic Interferometry enables exposure times down to 10 µs, so you can measure despite vibration, without isolation.
Wireless remote control makes it easy to set up long path measurements and to minimize disturbance of the optical path.
The optional Surface Isolation Source adds the ability to measure plane-parallel optics without coatings or back-surface treatments to eliminate unwanted reflections. Quantify shape optical thickness, transmitted wavefront error and homogeneity on optics as thin as 100 µm.
Motorized tip/tip and an adjustable-brightness alignment camera simplify fine adjustment. To complete your setup, 4D offers the broadest range of F/# spheres in the industry, and optical mounts, beam expanders and accessories for virtually any test setup.
4Sight™ wavefront analysis software, included with every AccuFiz, features excellent ease of use and a short learning curve. 2D and 3D displays, filtering, thresholds and masking tools make it easy to highlight surface shape and texture. Zernike, Seidel, geometric and diffraction analyses are easy to perform. Comprehensive data sharing capabilities let you read, write, save and print data in many common file formats for comparison between instruments. Optional 4Front™ software enables real-time measurement for system alignment, and fast averaging of many datasets.
A range of laser sources, aperture sizes, mounting components and accessories provides flexibility for a wide range of applications and budgets. Optional dynamic mode lets you measure despite vibration and air turbulence, without an air table.
AccuFiz is also an excellent upgrade for older interferometers and is compatible with most vertical stands or workstations from manufacturers such as Schneider, Graham, XONOX, OptoTech, TriOptics, OptiPro, etc.
